Clark (81 and 83), Assistant Trade Commissioner, at Lima, Peru, 
on August 36, 1937, repoited that although only 361,651 kilos of cute 
was exported from Fe.ru in 1936, as compared with 439,544 kilos in 1935, 
plantations have "been laid out on nearly all the rivers of the Amazon 
region, and good shipments are expected in the near future. Exports 
during the first five months of 1937 were 166,556 kilos, valued at 
439,217 soles. France was the principal purchaser in 1936, importing 
181,947 kilos; followed by England with 75,331 kilos; and the United 
States, which had been the largest consumer of the Peruvian root since 
1931, imported only 79,914 kilos, as compared with 263,113 kilos during 
1935. 
Dennis (114) in 1937 discussed the growing competition of Brazilian 
timbo with Peruvian cube. 
"Certain scientists, especially some in the Department 
of Agriculture -it Washington, unwittingly gave out the 
impression that rotenone was the toxic element in cube, when 
as a matter of fact it is the whole cube root that is valuable." 
"One reason for the arrival of so much from Brazil, in 
fact the main reason, was that the product was offered much 
cheaper, the average price was 6 certs a pound, while the • 
average of Peruvian cube was 11." 
"I also have a registered trade mark and hope to 
educate the trade to expect the trade name CUBE HOOT." 
Barrington (19, 20), Assistant Trade Commissioner, at Rio de 
Janeiro, Brazil, on September 30, 1937, reported exports of timbo from 
Brazil during January to June 1937, inclusive, to be as follows:

Timbo root 268,331 $ 25,175.25 
Timbo powder 1,030,57 7 19 1,996. 47

The northern States of Para and Amazon as are the largest pro- 
ducers of this product. Exports are made primarily from the port of 
Belem, Para. During 1956, shipments from Belem totalled 863,108 kilos 
(1,902,825 pounds), valued at 3,593 contos ($261,066). Six firms of 
that city were active in the trade, with two accounting for a. substantial 
share of the total. 
The United States Department of Commerce, Bureau of Foreign and 
Domestic Commerce, in October 1937 (440) published statistics for the 
first 8 months of 1937 and in '1938 (443) it published preliminary 
statistics on imports for the entire year of 1937 of rotenone-bearing 
roots into the United States.
